Let's break this down. We're going to add 2060 and 203 together.

Step 1: We'll start by adding the digits 0 & 3 in column 1 and get 3.

Step 2: We'll start by adding the digits 6 & 0 in column 2 and get 6.

Step 3: We'll start by adding the digits 0 & 2 in column 3 and get 2.

Step 4: We'll start by adding the digits 2 & 0 in column 4 and get 2.

So, 2060 + 203 = 2263.
